Two-wavelength Ti:sapphire laser for ozone DIAL measurements

Summary form only given. Laser remote sensing of ozone from aircraft has proved to be a valuable technique for understanding the distribution and dynamics of ozone in the atmosphere. Currently, the differential absorption lidar (DIAL) technique is used on either the NASA DC-8 or P-3 aircraft. There is also interest in deploying a system in an unpiloted ariel vehicle (UAV), which would require a total payload mass of <150 kg. The flash-lamp-pumped Ti:sapphire laser system is an emerging technology that could reduce mass and volume over the present system. In this paper, we discuss results from a Ti:sapphire laser having the capability of lasing at two different UV wavelengths, separated in time, from one flash-lamp pump chamber.
